Paper Abstract

Microtags are microscopic computer-generated holograms with 130-nm features and are mass- producible with EUVL. This fabrication method renders microtags difficult to counterfeit. Applications include tagging and tracking of microprocessors, memory chips, currency, and credit cards.
